Yes, but Firefox's profiles are very hard to use (apart from keeping multiple Firefox channels installed, e.g., stable, beta), I tried, and I couldn't.
Starting a profile is difficult, and also switching between windows, since the OS sees profiles as different apps. It's probably not hard to fix, but Mozilla has had other priorities.
